Bitter winds and hard frosts could be on the way.

THE days might be getting a little longer, but we might not be over the worst of the winter weather.

Forecasters are warning that a phenomenon, known as a sudden stratospheric warming, could mean a very cold spell at the end of this month.

Daytime temperatures could struggle to get above 0degC, with a bitter wind and hard frosts. There is also a chance of snow, but forecasters say it is too early to tell.

Channel 4 weather presenter Liam Dutton said: "Much of this winter has seen the weather alternate between cold and mild across the UK.

"Despite this, there haven't been any prolonged spells of intensely cold weather. However, there is a chance that this may change later in February.

"A few days ago, sudden stratospheric warming took place 10-50Km up in the stratosphere. More often than not (66% of the time), this increases the risk of colder than normal weather 10-14 days later.

"This often comes in the form of slow-moving areas of high pressure and bitter easterly winds.

"Whilst the occurrence of sudden stratospheric warming increases the chance of cold weather, it's by no means a guarantee. How cold it gets and for how long are dependent on the position of high pressure close to or over the UK. To get very cold weather, the high pressure would need to be over Scandinavia."

The long-term forecast from the Met Office predicts dry conditions dominating the UK throughout next week, with overnight frosts becoming widespread.

Temperatures of around average for the time of year at the start of the week will turn much colder by the end of the week, with some wintry showers.

From March 2 to 16, there will be a greater chance than usual of easterly winds developing, which would bring very cold weather at times and the potential for some snowfall in eastern and even southern parts.
